The invention relates tosink top construction. One object of -the invention is to provide an improved sink tep--constructionwhich facilitates the installation of a top-liner.

Another object oftheinventionis to provide a sink top construction which includes a preformed frame which hasa contour conforming around the sink.

Other objects of the invention will appear from the detailed description.

The invention consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a perspective of a sink-top embodying the invention, parts shown in section for illustrative purposes.

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1, through the sink, the frame, and mat mounted on the base with the top liner of linoleum installed thereon.

Fig. 3 is a detail perspective of the frame.

Fig. 4 is a perspective of the mat which is secured to the frame.

The invention is exemplified as applied to a sink-bowl I i] which is provided with an outwardly projecting continuous flange forming a rim Ii the margin of which fits in an opening in a structural top M which is usually formed of Wood and. serves as a shelf or drainboard for use with the sink.

The invention comprises a frame, generally designated I6, which corresponds in contour to the top rim of the sinlnbowl iii and includes a laterally extending flange l'i adapted to overlie the rim l l of the bowl and an integral upstanding flange IS, the inner face of which is downwardly convergent or curved to its meeting line with the sink. The frame It extends continuously around and over rim I l and is preferably formed of metal. The inner face of flange l8 which is exposed, is usually provided with a finish, such as chromium or nickel plate for appearance.

A mat I 9 has an opening 20 therein with its margin conforming to and fitting around the outer face of flange Ill. The bottom face of the mat fits on the top of flange l1 and is permanently secured thereto, for example, by rivets 24. The outer margin of mat l9 projects laterally beyond the flange ll of frame it into overlapping relatlon with and supports said frame on the structhereto cflnstitutes aprefabricated unitwhichqfits over'the rim on, bowlqifl and overlaps and is supsported-by :the structural .top 14.: for supporting; a :t op=linerz 25. of; material, such as linoleum. around ;;the-;bo wl., "The upstandingyflange Minis of -sumgcient'zheightso it will be flush with thatopz'face =50 thelinoleum when the latter is laidqngthesmat 1,19. .c'ihis shat may-,beformed .and cut. of,;.any suitable sheet material, such as pulp boardcr material commercially known as ffMasonitef :In'iinstalling the linoleum liner 25, it is only necessary to cut an opening therein conforming to face 23 of the upstanding flange l8. A filler layer 2? of suitable sheet material, such as Masonite is laid on the structural-top l4 and has a thickness corresponding to the thickness of the mat [9 so that the mat and layer will provide a flush surface on which the linoleum may be laid and cemented. A metal molding for providing a trim or finish for the front edge of the structural-top l4 and the linoleum top 25 comprises a vertical flange 3t and a horizontal flange 3| which is co-planar with the mat It.

In the use of the invention, the frame and mat are preferably prefabricated as a unit to fit the rims of sink-bowls of standard sizes. When it is desired to install on the structural top a top-liner of linoleum, the assembled frame I6 and mat [9 are placed on the top of the rim ll of bowl ii! and the top-face of the structural top i l. The filler layer 21 is then laid on the structural top I i so that it will be flush with the top face of mat it. An opening is then cut in the linoleum to conform to the face 23 of flange M of the frame it. The linoleum is then laid on the mat i9 on the filler layer 21 and cemented thereto. The upper edge of flange I8 of frame it will be substantially flush with the top face of the linoleum so that the liner Z5 and frame .16 will present a finished appearance. By prefabricating the frame with the mat, the installation of the linoleum liner is greatly expedited.

The invention exemplifies a sink-top construction which can be readily installed over the structural top and the rim of a sink-bowl without requiring skilled work. The invention also provides a single frame which forms an edge trim for the linoleum around the bowl and conforms to the contour of the bowl for attractiveness in appearance.

The invention is not to be understood as limited to the details described, since these may be modifled within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

1. A top construction for a sink provided with a rim, comprising a one-piece frame and a surrounding mat, pre-assembled for unitary placement on the sink, the frame having contour corresponding to, and overlying the rim of the sink, and being provided with integral upstanding and outwardly extending flanges, the mat fitting around the upstanding flange, and projecting outwardly from the laterally extending flange for overlying a portion of astructural top around the sink and providing a surface for supporting a top-liner of linoleumor the like, around the. upstanding flange.

2. A top construction for a sink provided with a rim, comprising a one-piece frame and a surrounding mat, pre-assembled 'for unitary placement on the sink, the frame having contour corresponding to, and overlying the rim of the sink and being provided with integral upstanding and outwardly extending flanges, the mat fitting around the upstanding flange, being fixed to and projecting outwardly from the laterally extend- "ing flange, for overlying a portion of a structural top around the sink and providing a surface for "supporting a top-liner of linoleum or the like,

. around the upstanding flange.

3. A top construction for a sink provided with a rim, comprising a pre-assembled one-piece frame and a surrounding mat, pre-assembled for unitary placement on the sink, the frame having contour corresponding to, and overlying the rim of the sink, and being provided with an integral upstanding flange having a vertical outer face and outwardly extending flange, the mat fitting around the upstanding flange and projecting outwardly from the laterally extending flange for overlying a portion of a structural top around the sink and providing a surface for supporting a top-liner of linoleum or the like, around the up-'- standing flange, the outer face of I the vertical flange adapting the top-liner to be laid from above, onto the mat and around the upstanding flange with the upper edge of the upstanding flange substantially flush with the top-face of the top-liner.
